All models of the Hyper Vest are equipped with side lacing on each side. In order to create a looser or more snug fit all you have to do is pull the cord on the side of the vest until you reach the desired fit. We recommend tightening or loosening from under the arm all the way down the side. Once the toggle is cinched tie an overhand knot under the toggle to keep in place. Simply tie any excess lacing behind your back or weave back through lacing to keep out of the way.
